ACF CPT Breadcrumb

Hello,

Please remove all previously shared filters and try using the following filter:

add_filter( 'rank_math/frontend/breadcrumb/items', function( $crumbs, $class ) {
        if(get_post_type() == 'car-brands') {
                $parent = ['Car Brands',
		           'https://rankmath.com' //replace with the URL of the page
		          ];
	        array_splice( $crumbs, 1, 0, array($parent) );
        }
	return $crumbs;
}, 10, 2);

Let us know how that goes. Looking forward to helping you.
